Process Challenge Devices
the new standard in cleaning verification
Why evaluate cleaning?
Cleaning is the only process that physically removes contamination from instrument surfaces and only clean surfaces can be effectively disinfected and sterilised.
Cleaning is considered the most difficult and most important of all decontamination procedures.
Routine verification of cleaning processes is essential to ensure compliance, and patients and staff safety.
“It is essential to evaluate all surfaces at the same time to properly verify the cleaning process”
VeriTest Tags: realistic challenge for realistic results
VeriTest Tag is made from 316L stainless steel to cover the largest proportion of surgical instruments.
VeriTest Tags are uniquely shaped to ensure you always fit them in the VeriTest Multi correctly. In addition, each tag comes inoculated with unique non-synthetic protein-based test soil.

VeriTest Blue: detects protein residue in minutes
VeriTest Blue is a protein detection system, a vial containing Aseptium’s protein sensitive reagent – VeriTest Blue – developed especially for VeriTest Tags.
To verify the process, simply insert the VeriTest Tag into the vial. If proteins are left on the VeriTest Tag after the cleaning process, the reagent will change colour from light green-yellow to blue, or blue residue will be visible on the tag surface.
verify multiple cleaning challenges at the same time
multi-dimensional surgical tools need multi-dimensional cleaning verification approach
VeriTest Multi: four-dimensional cleaning verification
VeriTest Multi verifies quality of cleaning of multiple cleaning challenges at the same time: shadowed bottom surface, narrow gap, angled vertical surface and top surface.
Typically, process challenge devices only test one surface in one orientation. Since all surgical instruments are multi-dimensional and are not cleaned evenly all around, it is essential to evaluate all surfaces at the same time to properly verify the process.
